Origin
Meaning and origin of Delarber
The surname DELARBER is of French origin, originating in the northern regions of France during the medieval period. It is believed to have derived from the Old French words "de l'arbre," meaning "of the tree," possibly indicating that the earliest bearers of this name lived near a significant or distinctive tree.
One of the earliest recorded instances of the DELARBER name can be found in the Livre Terrier, a medieval French land registry dating back to the 13th century. This document mentions a certain "Jehan Delarber" as a landowner in the village of Coucy-le-Château, located in the Picardy region.
Another notable historical reference to the DELARBER name appears in the Répertoire de Noms de Famille, a comprehensive compilation of French surnames from the 16th century. This work includes several variations of the name, such as "Delarbre," "Delarbe," and "Delabre," suggesting that spelling variations were common during that time.
One of the earliest known bearers of the DELARBER name was Jacques Delarber (c. 1550-1625), a prominent merchant and landowner from the city of Rouen in Normandy. Records indicate that he played a significant role in the local economy and was involved in the trade of textiles and spices.
Another notable individual with the DELARBER surname was Marie Delarber (1678-1745), a French botanist and gardener who was renowned for her extensive knowledge of medicinal plants. She authored several influential works on herbal remedies and was a respected figure in the scientific community of her time.
In the realm of literature, one cannot overlook the contributions of Étienne Delarber (1790-1862), a celebrated French poet and playwright. His works, which included several acclaimed plays and poetry collections, were widely acclaimed for their vivid imagery and exploration of human emotions.
During the 19th century, the DELARBER name gained prominence in the field of engineering with the work of Léon Delarber (1825-1901), a pioneering civil engineer who played a crucial role in the construction of several major infrastructure projects in France, including the iconic Eiffel Tower.
Lastly, it is worth mentioning André Delarber (1905-1987), a renowned French artist and sculptor whose works were celebrated for their unique blend of traditional and modern styles. His sculptures adorned many public spaces and galleries across France, earning him widespread recognition as one of the most influential artists of his time.

The bar chart below shows how Delarber bearers described their own race and ethnicity on the 2020 Census form. The Census Bureau groups responses into six broad categories: White, Black or African American, Hispanic or Latino, Asian and Pacific Islander, American Indian and Alaska Native, and Two or More Races. When a category has too few respondents for a given surname, the Bureau suppresses the figure to protect individual privacy, which is why some names show fewer than six slices.
Percentages are shown for every Census year so the breakdown stays comparable over time. When the source file also includes raw headcounts, Name Census shows those alongside the percentages in the legend.
Keep in mind that these are self-reported numbers. A person's surname does not determine their race or ethnicity, and the distribution you see here reflects the specific population who happened to carry the Delarber surname at the time of the 2020 Census, not any inherent property of the name itself.
